Yep, still pretty good fishing. At least it was two summers ago.... Was VERY good in the old days, and seemed to be starting to come back in the past couple of years. Agreed with wish2hunt regarding lures, though my primary the last few trips has been a fly rod with streamers for the smallies and nymphs for the browns/rainbows (generally fish up-river far enough to get into plenty of trout). Have also had great luck with black rooster tails if using spinning gear. As to whether it is open or not, you should call the San Carlos tribe to confirm. Also be aware that if you are going to fish or access the north side, you need a White Mountain permit.
Regarding location, do a Google search for the 'pump station' on the Black river (Point of Pines is a reference point to get you in the rough area on a map). Look for the 2000 road NE from Point of Pines, and then take the 1560 road to the river from there. Pump station is well known, so not giving away anybody's secret spot there. Good place for an initial trip to get to know the rough area, and then you can explore from there to find your own honey holes.
